PARDO G, Mario; SEPULVEDA P, Sergio; CUEVAS G, Claudia  and  DIAZ G, Carolina. BIOPSIA QUIRURGICA CON MARCACION PREOPERATORIA EN LESIONES NO PALPABLES DE LA MAMA: EXPERIENCIA DE 10 AÑOS. Rev. chil. obstet. ginecol. [online]. 2003, vol.68, n.5, pp.387-391. ISSN 0048-766X.  http://dx.doi.org/10.4067/S0717-75262003000500005.

Background: The sistematic use of mammography and ultrasound have increased the diagnosis of non-palpable breast lesions and the indications of biopsies. Aim: To evaluate ten years of surgical biopsies of nonpalpable suspicious breast lesions. Material and Method: We present our experience in 315 excisional biopsies from occult breast lesions with preoperative localization. We used mammography in 83.8% and ultrasound in 10.5% of our cases in order to place a metallic wire. Ultrasound guided us to localize the occult lesions in 5.7% of the cases, placing a mark over the breast skin. Results: We obtained 21.2% of malignant tumors, 17.5% of atypical hyperplasic and 60.3% of benign pathology. We could not obtain an adequate specimen in 1% of the cases (three patients). Discussion: The incidence of 21.2% of malignant pathology is consistent with data published in the general literature (20 to 30%). If atypical hyperplasic specimens were added, the positive results would be increased to 38.7%. More than half of the lesions are benign. Improvement in sensibility and specificity of the diagnostic methods are essential to avoid unnecessary surgeries
